Elephant Gun
An elephant gun is a large caliber gun, rifled or smoothbore, originally developed for use by big-game hunters for elephant and other large game. Elephant guns were black powder muzzle-loaders at first, then black powder express rifles, then later used smokeless powder cartridges. Early use As Europeans made inroads into Africa in the early 19th century, guns were developed to handle the very large game encountered. This was for self-protection, food gathering, and sport. The first guns were the simple muzzle-loading shotgun designs already used for birds and loaded with solid balls of lead for use on large game. Due to their ineffectiveness on the largest game (up to 35 shots being recorded by some writers for a single elephant), they soon developed into larger caliber black powder smoothbores. The caliber was still measured in bore or gauge—10, 8, 6, 4 bore, and 2 bore—or the guns were named by number of projectiles per pound. The projectiles were lead round ball ...

Antimony
Antimony is a chemical element; it has chemical symbol, symbol Sb () and atomic number 51. A lustrous grey metal or metalloid, it is found in nature mainly as the sulfide mineral stibnite (). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name Kohl (cosmetics), kohl. The earliest known description of this metalloid in the West was written in 1540 by Vannoccio Biringuccio. China is the largest producer of antimony and its compounds, with most production coming from the Xikuangshan Mine in Hunan. The industrial methods for refining antimony from stibnite are Roasting (metallurgy), roasting followed by carbothermic reaction, reduction with carbon, or direct reduction of stibnite with iron. The most common applications for metallic antimony are in alloys with lead and tin, which have improved properties for solders, Bullet, bullets, and plain bearings. It improves the rigidity of lead-alloy pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

505 Gibbs
The .505 Gibbs cartridge was designed by George Gibbs in 1911. The cartridge was originally known as the .505 Rimless Nitro Express. The C.I.P. refers to the cartridge as the 505 Mag. Gibbs in their publications. It is a .50 caliber (12.8 mm) rimless bottlenecked cartridge intended for magazine-fed rifles. General information The .505 Gibbs has a case capacity of of water. This cartridge was originally loaded with of cordite and bullet at for of kinetic energy. While the .505 Gibbs has a greater case capacity than most modern cartridges, it is loaded to lower pressures. The C.I.P. recommends a pressure of for the cartridge. As .505 Gibbs was intended for hunting dangerous game in tropical environments, and due to the temperature sensitivity of cordite, the lower pressures provide a greater safety and reliability margin. The .505 Gibbs has a unique bullet diameter of while most other .50 caliber bullets have diameters of . Barnes Bullets and Woodleigh Bullets are a ...

404 Jeffery
The .404 Jeffery is a rifle cartridge designed for hunting large, dangerous game animals, such as the " Big Five" (elephant, rhino, cape buffalo, lion and leopard) of Africa. The cartridge is standardized by the C.I.P. and is also known as .404 Rimless Nitro Express. It was designed in 1905 by London based gunmaker W. J. Jeffery & Co. to duplicate the performance of the .450/400 Nitro Express 3-inch in bolt-action rifles. The .404 Jeffery fired a bullet of .422 in (10.72 mm) diameter of either with a muzzle velocity of and muzzle energy of or with a muzzle velocity of and of energy. It is very effective on large game and is favored by many hunters of dangerous game. The .404 Jeffery was popular with hunters and game wardens in Africa because of its good performance with manageable recoil. By way of comparison, the .416 Rigby and .416 Remington Magnum cartridges fire .416 in (10.57 mm) bullets of 400 gr (26 g) at with a muzzle energy of approximately . These ...

__NOTOC__ Year 416 ( CDXVI) was a leap year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Theodosius and Palladius (or, less frequently, year 1169 ''Ab urbe condita''). The denomination 416 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Ballistite
Ballistite is a smokeless propellant made from two high explosives, nitrocellulose and nitroglycerine. It was developed and patented by Alfred Nobel in the late 19th century. Military adoption Alfred Nobel patented Ballistite in 1887 while living in Paris. His formulation was composed of 10% camphor and equal parts nitroglycerine and collodion. The camphor reacted with any acidic products of the chemical breakdown of the two explosives. This both stabilized the explosive against further decomposition and prevented spontaneous explosions. However, camphor tends to evaporate over time, leaving a potentially unstable mixture. Nobel's patent specified that the nitrocellulose should be "of the well-known soluble kind". He offered to sell the rights of the new explosive to the French government, but was declined. Modern research shows that Vieille already discovered it in 1884-1885, about the same time as his Poudre B, and noted its high flame temperatures leading to bore erosion. ...

Poudre B
Poudre B was the first practical smokeless gunpowder created in 1884. It was perfected between 1882 and 1884 at "Laboratoire Central des Poudres et Salpêtres" in Paris, France. Originally called "Poudre V" from the name of the inventor, Paul Vieille, it was arbitrarily renamed "Poudre B" (short for ''poudre blanche''—white powder, as distinguished from black powder) to distract German espionage.Davis, Tenney L. ''The Chemistry of Powder & Explosives'' (1943) pages 289–292 "Poudre B" is made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% paraffin. "Poudre B" is made up of very small paper-thin flakes that are not white but dark greenish grey in colour. "Poudre B" was first used to load the 8mm Lebel cartridges issued in 1886 for the Lebel rifle. History German-Swiss chemist Christian Friedrich Schönbein created the explosive substance nitrocellulose, or "guncotton", in 1846 by treating cotton fibers with a nitric acid and su ...

Nitro Express
The Nitro Express (NE) series of cartridges are used in large-bore hunting rifles, also known as elephant guns or express rifles, but later came to include smaller bore high velocity (for the time) British cartridges. Name The term "Express" was coined by James Purdey in 1856, derived from the express train, to publicise the bullet velocity of his double rifles and became common parlance for many rifle cartridges. The addition of the word "Nitro" stemmed from the propellant used in these cartridges, cordite, which is composed of nitrocellulose and nitroglycerine. Evolution Early developments The unveiling of the .450 Nitro Express by John Rigby & Company in 1898 heralded the beginning of the modern big-game cartridge. Created from loading the already popular .450 Black Powder Express with cordite, the .450 NE was a fast and accurate cartridge capable of taking all African and Indian dangerous game. Early extraction problems with the .450 NE was the catalyst for Holland & ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
